BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unloader / loader in which a pneumatic unloader for sucking and landing granular loose materials such as grains and a loader for loading the loose materials by an in-machine conveyor are combined.

[0002]

2. Description of the Related Art Granular materials such as grains that have been sucked and landed from a ship by a single device are sent to a ground conveyor via an in-flight conveyor or discharged from a silo and sent by a ground conveyor. An unloader / loader is one that transports the cargo to a small ship such as a barge by a loading chute and transfers bulk materials sucked from this ship to a small ship by a loading chute through the in-machine conveyor.

As described above, in order to load the bulk items from the main ship to the barge, the main ship and the barge must be moored side by side. Therefore, a waterway for small ships such as barges will be provided inside the quay, the ship will be moored to the outer quay outside the waterway, and the barges will be moored to the waterway for small ships.

The unloader / loader includes a sea leg on the outer quay on the sea side of the waterway and a land leg on the inner quay on the land side of the waterway.
It has a portal frame that connects them and has a traveling frame that travels across a waterway for a small boat. A boom is attached to the tip of the traveling frame on the sea side so that it can be swung up and down, and the boom holds a suction pipe on the lower side thereof. The bulk material sucked up by the suction pipe from the inside of the ship reaches the receiver tank, where the air for suction and the bulk material are separated, and the bulk material is transferred to the in-flight conveyor installed on the portal frame, It is transferred to the ground conveyor. When the bulk items are reloaded on the barge without being transferred to the above-ground conveyor, the switching chute provided in the middle of the in-machine conveyor is operated to flow the loose items on the in-machine conveyor to the loading chute.

[0005]

However, the conventional unloader / loader as described above has the following problems. In other words, the landing time from the ship is long, but the number of times is small. On the other hand, the loading time on each barge is short, but the number of times is large. For this reason, depending on the circumstances of the ship, it may be desirable to moor a barge to the outer berth for loading when there is no ship, but the conventional unloader / loader described above cannot handle this, and a separate loading loader must be provided. there were.

The present invention has been devised in view of such problems of the conventional unloader / loader, and an object of the present invention is to provide an unloader / loader that can be loaded even when a barge is moored to the outer quay.

[0007]

In order to achieve the above object, an unloader / loader of the present invention has a sea leg, a land leg, and a portal frame connecting them, and has a small boat waterway sandwiched between an outer quay and an inner quay. A traveling frame that straddles and travels, a boom that is attached to the tip of the traveling frame on the sea side so that it can be undulated and swiveled, and that holds the suction pipe. A receiver tank that separates, an in-machine conveyor that is installed on the portal frame and that conveys loose material from the receiver tank to the above-ground conveyor, an inner loading chute that is undulated and stretchably attached to the land-side lower surface of the portal frame, and a portal.
